The n om it mag/concern own that I, J oHAN LnvNnMArvN, of Copenthe Kingdom of Denmark, have invented a seful Improvement in Turrets for Iron-Glad nd vI do hereby declare the following to be r, and exact description of the same, referg had to the annexed drawings, making a is specification, in whichl is a side elevation of an .iron-clad vessel, he adjustable turretsin a position Vextendthe deck.

2 is a top view of an iron-clad vessel, showadjustable turrets.

3 is an elevation of an adjustable turret, conn shelter one sentry.

4 is an elevation of an iron-clad turret, cona shelter two or more, sentries, and showing r raising or lowering the adjustable turret. ne letters of reference, in all the iigrues, deical' parts. l

ntion consists in providing iron-clad vessels r more adjustable turrets or iron-clad sentryturrets being so constructed that they may levated above the upper deck ofthe vessel, so rn uch that the top ofthe adjustable turret el with the upper face of the deck. djustable turrets are provided for the purrotecting sentries against the bullets of an d thereby preventing the enemy, by a surboarding the iron-clad and taking possesupper deck.

le others skilled in the art to make and use ement, I will proceed tc describe its construcperation.

Fig. 3 represents aminor turret or Sentry-box, in which one sentry may be posted.

The turret E is constructed in such a way that the upper part of its wall is built in a substantial way, and the outside covered with iron plates, in order to preventany shot iired against it from penetrating.

This upper part of the turret is provided'with a.

suitable number of oblong apertures., I, which may be opened or closed, by means of shields or movable circular platesl attached to the inside of the turret.

These apertures I may be large enough to admit one or two muzzles of fire-arms. (Short breech-loading riiies are proposed.) There may be two movable circular plates or shields, one above the other', so arranged that two sentries may fire through the same aperture I" at the same time; or if only one muzzle is placed in the aperture, then the shield will cover halt' the opening. By such arrangement, the sentry or sentries placed in the turret are less liable to be shot by a surrounding enemy. 1

The lower part of the turret is constructed with vertical supports K K K, duc., on which the top part rests. These supports Ii, Sac., are placed so far from each other that a man can pass between them, and have an easy ingress and egress to and from the turret. The height of the turret will admit of a man standing upright, and it must be capacious enough to permit the Sentry or sentries within to handle his or their fire-arms without any incurnbrance. The turret may have any desired shape, but I prefer va circular form.

Fig. 4 shows a device by which the turret may be raised or lowered.

L is a vertical support, on which the turret rests.

I is a pulley, secured to the vertical support L, a little below the door of the turret.

M is a lever, with one end bearing on the lower part of pulley L, and its other end is provided with a weight, O, and secured to the middle deck by a hook or strap, I.

The adjustable turret may be lowered so far down that its upper surface is level with the surface of the upperdeck. The lowering of the turret is accomplished 'by the following method:

The hook or strap I being withdrawn, the turret then descends. As the weight O does not quite counter-balance the weight of the turret, the descent will be performed in a few seconds, (the distance of lowering or raising the turret being limited to about two feet,) Without any exertion and eirpenditure of labor. The lever M will turn on its fulcrum N, and the turret will descend until it rests on the. projecting ridge I which fits into a recess, A', cut for that purpose in the upper deck. When it rests in the recess A', .its upper surface will be on a levelwith the surface of the deck.

The upper part of the turret may bev provided wit a coating of caoutchouc, which would t snugly inthe recess cut inthe upper deck, and Vprevent water from penetrating.

Speaking-tubes might be used, and serve to place the sentry in the movable turret in communication with the commander of the ship.

the purpose set forth.
